To all whom t may concern Be it known that I, RICHA'RD H. THOMAS,

a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinols, have invented certain new and useful Im rovements in Reservoirs and Pumps There or; and I do hereby declare that the following is a full,`clear, and exact description of the same, reference being had: to t e accompanying drawin and.

tant usually to economize spnce.to the utmost and at the same time toaordas large a reservoir as possibleforthe reception of ythe sewage, and .where centrifugal pumps are employed', itis very important tov so install' lthe Samaras-.to enable the engineer' .or workmen 'to have access tothe sament all times. It is alsoimportant to catch the solid constituents inthe fluid for `independent removal, to `prevent the same `passing through andpossibly foulingthe pumps.

It is an object `of this inventionzto afford thelargest possible reservoir for the space e and to afford in connection` there-` availab with adry chamber for the pump or pumps contained thereind, located vbelow the `normal leveloflthe liqui in the .-reser oira.

Itis also an object ofv the invention to afford. a construction by means of which the pumps may be' startedautomatically with` the rise of the liquid in the4 reservoir.` above a redetermined level andetoppedautomati-` ca ly when the level of theft-liquid 1n therese ervoir has heen-sullciently reduced..

It-is also anobject of the inventlon to ,afford a construction inK which the pumps and. all parte connected therewith, areso stalled as to permitzinspection-at any timeandl in which the operatlon of the pumps is` controlled froman operating floor or level at tlie @top of the reservoir.

Fig. i2 is a con' trulsection taken on line 2-2 oi Fig. l. F 1g.` 3 is a top plan View thereof. Fig. 4 is `a section taken on line 4 4 of Fig. 1. Fig. 5 is an` enlarged, central vertical section of the inlet ipe and collector for the solid y ig. 6 is an enlarged fragmentary section broken' away, of the main suction pipe for the pump. Fig. 7 is a similar View of the suction pipe for the pump well. Fig. -8 is an enlarged view in side elevation of the controllin switch. Figf) is a section xon line 9,-9 o Fig. 8. y vAs shown in the drawings: The reservoir 1, is cylindric and constructed of sheet metal and is provided with axbottom 2, also ot' sheet metal or otherl suitable material, connected inthe lower endthereof. Positioned axially Within the reservoir is an inner the `operativeinstallation ofthe pumps 5,l

which, in the drawings, are shown as two in numben Said umps are .centrifugal pumps of a fami iar type, the particular construction of which forms no part of this invention, 'as it is to -be understood that any suitable pumps may be employed. Said pumps are mounted on the floor or bottom 4.

`of the pum well to rotate in a horizontal p1a`ne,and e eduction or dischare pipe 6,

thereof connects in afriser 7, Whici extends upwardly above the top of the receptacle to a height suiiicient to permit the same to dis`` charge to the sewer or other place of discharge for the contents of the reservoir, de-

pend1ng,; of course, upon the purpose for so upon which the device is installed, and a ythe character'and position of the installa-` Communicating throughflthe side-wall 1, of the reservoir, near the top thereof, 1s the `inlet pipe 8, for the sewage. This inlet pipe 1s provided at its inner end with a T fitting 9the branch or stem ofwhich is screwed on said inlet pipe` and the' ends 'of' which -are directed upwardly and downwardly rejspectively. Thel lower end of the' T is provided with a peripheral, inwardly ,directed ange 10, affording an. inwardly projecting shoulder, and vinserted throu h the Tfand rest-ing on said flange or shoul er 10, is an elongated basket `11, ofwire net, or any suitable perforated or reticulated material for the collection of the solid matter from the sewage. Said basket is open at it-s upper end-and connected thereon;is a bail 'wise open mouth of the` suction head 15,

of each of said suction pipes, is a sheet of wire net 15 or other erforated-material,

whichl acts to exclude rom'the pump. any

solid material that might have been discharged into the reservoir. Also connected with the suction pipe of the pump a suction Vpi e 16, *for kthe pump well,the end of whic is directed downwardly to near the floor of the pump well and is provided with a flaring head 17, likewise havingthe mouth thereof covered by wire net 18,' or'other-perforated material as fshown in Fig.r7.

' Valves 19 and 20, are connected in the suction pi e for the reservoir andthe suc` well, and the valve stems are provide wit hand wheels 21. and

tionpipe or the` um 22, lpositioned convenient-ly v with reference to t e pumps and whereby the valvesv may be operated,` if desired, b v the workman or engineer in the pump well. Connected with each of said valve wheels is an extension rod 23 and 24, which extend u wardly above the to of the reservoir an 1 through the metallic or other cover L2 5, as shownln Fi 1, and above said cover is provided wit hand wheels 26 and 27, thus enabln an operator to open orclose said valves wit out thenecessity of descending into the welL .The respective branches of the discharge pipe 6, are also each provided with va valve 28, also having a-.hand wheel 29, for` operating the same adjacent the pump and an extension rod 30, which extendsI through the suction pipe 1 3, for each vsired cover and isfprovided Vvvit'hra-ha'nd wheel 31, l

yas before described with reference to the valves for the respective suctionpipes.

Mount-ed upon the @over or floorabove the reservoir `and,'of course, upon any suitable support, are motors32, one for )each pump.

These are shown as electric motors, and the shaft 33, of each is coupled to the pump shaft l34, which extends upwardly through the cover 25, for that purpose.v l

A ffoat operated `switch 1s provided for starting and stopping the pumps. AFor this purpose, as shown, a.` switch board 35, is provided for each motor andprovidedwith lcontacts 36, suitably connected with the leads from the motor. 'Pivotally supported on the board between the contacts 36, on each side of the board, is a switch bar 37, provided at itsends with contact members for engaging the respective contacts 36. In-

tegrally connected with said switch vbarv and extending `upwardly therefrom,` is a weighted arm'- or lever 38, and engaged thereon is a. lever 3 9, which extends along the face of the switch board and beyond the same. Said leverisprovided with a yokedendV 40, throughwhichlis slidably engaged a rod 41, which extends through; a sleeve .42,

.mounted on the coverl and through said cover 25, into the reservoir, and at its lower end is provided with a float 43," atl all times supported on the liquid in thel reservoir.

Projections or balls 44 and 45, are secured on said float rod 41, a sufficient distancev apart. that the `upper projection "44,

end `thereof downwardly, thereby shifting the switch bar out of engagement with the contacts and swinging the weighted lever 38,v

past the centerof its support'to maintain the switchlbar'out of circuit when the liquid inv the reservoir is at its lowest level. distance between the ballsor projections ,-44

and 45, on said loat rod, however, is such ermit the reservoir to ll to the A,de-a

as to eight before shiftin `said lever 39, upwardly, or, in other wor s, bringing the switch` bar into engagement with the contact members 36, -to start the` motors and pumps. When -this occurs, the weighted ever 38, is swung past the center of its support onth'e opposite side to maintain the The 10@ will engage said lever .39, to pull the yoked f contact until the pumps have reduced 'the level in the reservoir to', a minimum. Conveniently, said projections or balls are ad-- justably secured by means vof set screws' 46 late the starting and -sto ping ofthe motors for the height of liquid :In the reservoir preferred. i t

The operation is as follows: Theconstr'uctionin which' the pump well is installed ,within -the` reservoir "and axially thereof,

Iso l operators, a man hole 48, bein Iprovided suction pipes simultaneously:` Should the .in .the cover for sthat purpose., hould any vmoisture or water accumulate in the pump well, it is only necessary to` open the valve` 20, in one of the suction pipes for the well to enable the well tobe promptly pumped dry, audit is 'immaterial whether the valve for the suction pipe of the 1reservoirbe closed r not, inasmuch as the capacit of the pump is suflicient; to drawfrom th uantity to be pumped require not Amore t an one pump, the valve 28, .in` the discharge, pipe"` for the pump not 1in eumirnis` sion, may -be closed, andthe balls or'projecti'ons on the float rod for actuating theV switch for the motor for that .pum maybe released from the rod to permit t e rod to slide freely up and down therethrough,V thereby permitting the switch to *remairnn the osition shown inFi 8, or, inother wor s, withthe circuit bro en.' When sew' age is admitted,`it is strained in the basket, the liquidV constituents passing into the reservoir and all solid material being collected in the basket.` This is, ofcourse, dumped from time to timeas occasion may require, thereby 4 reventing the clogging `of the he screened suction ipes inthe reservoir further revent the discharge of solid material to e umps. Of course, inasmuc as the arm 39,1oosely` engages the jfioat rod, the `operator may swing the lever 38, manually to either side of thecenterof its su port, thus throwin the motor and pump or the switch` boa operated, .into action or out of action, as he mag prefer. f course,it is to be understood that while I have referred to a `reservoir constructed pensable as the wa sand bottom and `also the pump well, may be constructed of any material suitable for the purpose. Details of construction and arrangement may be varied without departin from the principles of this invention. I4 ierefore do not urpose limiting; the tent tobe grants `on this application, ot erwise than necessitated by the prior art. Y l
